// Version 2.2 // C # // Accept control other than a Form // You can add your own print functions for specific controls and for report title formatting // Controls can expand // Expendable TextBox multiline added // Expandable ListBox added // Expendable FlexGrid added (Grid from Component One: code in comments only [no references]) // DataGrid printing // More comments in source code // Report printed can continue on many pages // Can display a trace of controls printed // Can print page number using your own String.Format // Report can be print to a multiframe Tif file (example: for faxing) // Better algorithm to compute extension of container control with rezizable side by side childs // Test
